STRIP-TACK-J-IEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 383,278, dated May 22,1888.

Application filed February 8, 1888. Serial No. 263,862. (No model.)

In a slot made in its upper end (see 5 B is the shaft.

It also carries the cam H and crankback and forth on itspivot K.

The action of the tools proper, L L, is illustrated in Figs. 4, 5, 6,and 7 L is a heading-t00l attached to the lower part of the tool-holder,and L is a pressure: roller which serves to impart to the head a rollingmotion, which flattens or swages and at the same time evenly distributesthe head metal.

L is a gage, also attached to the lower part of the tool-holder.

My machine acts as follows: The strip-tacks are placed in the channel ofthe machine and fedto the point at which they are to be headed at thetime that the tools L L are placed as shown in Fig. 5. Now the firstaction of the machine is to move the toolcarrier in the directionindicated by the arrow in Fig. 6 and bend the head metal over to theinclined position shown in Fig. 6. Then the toolcarrier returns in thedirection indicated by the arrow, Fig. 7, and causes the roller L to actupon the head metal, flattening a part onto the fixed jaw H and causinga part to flow over onto the jaw H, thus making an even flat head.

If desirable, the heading-tool L, instead of being a fixed bar, asrepresented in the drawings, may be a roller similar to L.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a strip-tack-heading machine, the combinationofgripping-jawsforholdingtheblank, l

an oscillating operating-tool for bending the head in one direction, anda roller for bending or swaging the point or end of said head back uponitself in the reverse direction, substantially as described.
